CARBUBETEK- Specification of Letters Patent.

Patented Dec. 29, 11914.

Application flled-April28,1918. Serial No. waste.

To all whom it may concern:

Be it known that I, ALBERT J. Simmer, a

citizen of the United States, and a resident of Boston, in the county of Suflolk and State of'Massachusetts, have invented certain new and useful Improvements in Carburetors, of which the. following is a specification, reference being had to the accom panying drawings, forming part thereof.

This invention has reference to improvements in carbureters for gas engines and relatesto the construction of the carbureter and its fluid delivery pipe.

invention is to facili- One object of the gaseous fluid tate the transmission of the from the carburetor.

Other objects of the invention will appear from the following description.

The invention consists in providing a carburetor with mechanical means for moving forward the gaseous fluid from the carbureter.

The invention also consists in such other novel features of construction and combination of parts as shall hereinafter be more fully described and pointed out in the Figure 1, represents a side elevation of the improved carburetor, parts of the same being broken away. Fig. 2, represents a vertical sectional view of the same.

Similar characters of reference designate corresponding parts throughout.'

Under conditions of low temperature the quality and condition of the .air and gas or gasolene combined in the carbureter the gaseous fluid through lack of sufficient expansion often clogs the carburetor. At

times also the mixture of air and gas in the carburetor is not 'sulficlently homogeneous to afford the'necessary degree of expansion,

and it is the main purpose of this inven-- tion to mechanically mix said fluid and to move the same forward toward the point of use.

In carrying this invention into practice I take a carburetor 5, preferably of the-float feed type herein shown and provide the chamber 6 thereof with the rotary collar 7 having the key 8 inside and the bevel pin- .ion 9 outside. Meshing with this pinion 9 is the pinion 1010f the rotatable shaft 11 which shaft has the pulley 12 adapted to be operated by any suitable means.

I Mounted above the chamber 6 is the pipe 13,having the inwardly extending blades 14, 14, which may be and preferably is the intake pipe of a gas engine manifold on a pipe leading to the gas engine connected with the neck 15 having the slidable valve 16. Journaled in a bearing of the pipe 13 is the fan shaft 17 having at one end the screw threaded portion 18 provided with the adjusting nut 19, and at the other end the key seat 20 which is slidably engaged with thelcey 8 of the collar 7 so that slfaft 17 readily may be engaged with said collar 7. Fixed to said shaft 17 is the agitator blade 21 and the fan blades 22, 22; agitator blade 21 extends into the carbureting chamber preferably to a point at or slightly below' the level of fluid therein indicated on Fig. 2 by line a-a.

In operation the fan shaft 17 may be adjusted somewhat by nut 19, so that its fan blades 22 clear the blades 14 of pipe 13 while the agitator blade 21 extends into the carbureter 6 and acts on the fluid in said chamber 6. By rotating pulley 12 shafts 11 and pinion 9 will be caused to rotate and the rotation of pinion 9 will be transmitted bv the key 8 to the agitator blade shaft 17 whereupon fan'21 will act to thoroughly mix the fluid in chamber 6, to drive the gaseous fluid'forward into pipe 13, wherebv'gaseous fluid is constantly supplied to said pipe 13 where it is further -mixed by the action thereon of the fan ters Patent,

1. A carburetor having a rotary shaft, an extenslon'fan chamber mounted on said carburetor, a fan having a 'shaft rotatably mounted in said chambei' and in slidable engagement with said carbureter shaft, an

agitator operated by said fan shaft and extending into said carbureter, and means for ad usting saidfan shaft longitudinally.

. 2. A carburetor having a rotary shaft, an extension chamber mounted on said carbu-- reter, a. fan shaft journaled in said fan her and having a screw thread, an adjusting nut engaging said shaft, said fan shaft slidably engaged with said carbureter shaft, a series of fan blades on said fan shaft, and

5 an agitator blade mounted on said fan shaft Within said extension chamber and extendmg into the earbureter. 3. A 'carbureter-ihavmg a rotary member,

:111 extension fan cl amber earried by said' 10 carbureter and having radially extending bafiles, a fan shaft rotatable in said fan cl1an1l3er and in engagement with said r0- tary member, said shaft having fans operating between said'baiiles, and an agitator
